description. l. invention.I such es Will enable othe in the nrt to whichit nppertninf" o. use. the se 'filly odtiptd in case of fire, thatsupposing :i building1 equipped a ot this design should'catch otherstructure in which it may be desirable to install. an alarm device, itwould cause. n bell in the building or strueture to ring `about tiveminutes or more, zml it would also muse on electric bell 'to notigT thelire le artinent. The above coinplished :evering or destroying a. cordrontrol'lingyj the hell sind movable Contact in the lruildino' oretrnotln'e; this movable rontnot controls tbe.ciro=.iit of the olectriobell, its will he further manifest.

This invention comprises further objects und combinations oi" elements'which will be hereinafter moree i'ull;VT described, shown in theaccompanying drawings, and the novel tentures thereof will be pointedout by the appended Claims.

'lo obtain a full sind correct understanding` of the details ofooiistruotion, ACombinetion of features, elements and advantages,reference is to be had to the hereinafter set "Tnth descrii'ntion :indthe accompanying drawings in connection therewith, ivherein theinvention is illustrated in a Single View, showing the Wiring for thedevice, and its principal tentures. I

linking' renewed reference to the accompanying drawings, wherein similarreference diameters indicate Corresponding' parte in the illustration,by figures, 1 designntesthe usual forni of n signing controlled alarmbell, which is provided with n lever 2, held against the tension of :tspring` (not shown) Within the hell, by ineens oit' the oord or cable 3or siniilnr inenns. which engages l(ind moves over a plurality oi'pulleys l ,suittlbly arranged Within n building or other structure sothat in case of lire the cord will be severed, thus releasing; thelever' 2, which Will cause the ll to ring until run clown, as will beun- -ited States, residing at vbell 18, as Shown.

a Collar 10g between which andthe said benring 9 a. Spring' 11 isdisposed, which has a tendencyv to 'torce the said contact outtv. rd, soas to canse a ContactA with d' stationary Contact 12, that is when theseid cord 3 is severedb7 lire. This Contact is insulated as I at 13which iS extended as at 11ito form a.

bearingfor the end of the movable. Contact S, as further shown. rthesitio. stationary Contact is provided'vfith a binding screw 15 by whichthe lend 16 is connected thereto, which lend 1G is connected to thebinding post 17 of the eleotrio bell 18:15 further shown; the lead 1G isprovided with a ont tery 19 which provides current or the apparatns.

Disposed Within the handle, which is of :in arched shaped design, ie nbinding,r screw F20, by which the lend Q1 is 'ield to the end oil themovable oont S, Clearly shoivn in the drawings. This lend 21 is alsooonnected to a. biiiding post 22 of the eleotrioi it will thus be seen,when the Cord 3 is severed, the movable oontaot and the lever 2 ot' theheil' 1 is released, thereby causing. the hell 1 to ring and closing thecircuit of the electric bell; the bell 1 notifies the occupants ot' theimildino and Y .w the electric bell 1S is desioned tonotii f the,

fire del'iartnient, by the @severing of the It is to be nnferstood thatvarious changes nud inodiiioutions muy be employed in the constructionand en'ibodinient therein, combination o1 tentures, und elements,without in any Waydepnrting from the spirit and scope oI" the inventioncovered by the Claims thereof; it being understood that Whatevervariations .or modifications :1re employed must fall within the scope ofthe appended claims.

From the foregoing, the essential features, elements and the operationof the device, together with the simplicity thereof, will be clearlyapparent.

Having thus @tullio tion, what is claimed e the protection of 'fvcribedthe invennexv and useful, by i)ntent is 1. it device of the .characterdescribed; comprising a stationery Contact having :t-

ltubular metal member and a corresponding insulating member yreceivingsaidA metal member, a movable contact of'rod-formation extending intoand slidable in said insulating member, a resilient member adapted todeliver its tension or stress upon said -slidable or movable contact,

means for producing an alarm, said movable contact being provided with afixed handle of baillike formation and connecting means between saidhandle and said alarm producing means, adapted to be readily destroyedby the action 'of a fire'.

2.1.In la device as set forth, a. stationary severed or contact having ahollovs7 bore a` portion of which is formed of insulating material, amovable `spring-actuated contact received thereby, said movable Contacthaving an larched shaped handle,

an eye integral there'- with, an alarm bell having a spring actuatedlever,

said lever, While the other end is connected means designed to engagepuls ley's, one end of which being connectedv toA to said eye7 saidmeans designed to control vsaid bell and the movable contact, and Wh'ensevered, said bell and Contact being released, an electric bell andbattery in' circuit With the stationary and movable contacts. v

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
